Footer widgets rows in Infinity Pro

Would you please create a tutorial that shows me how to add an 100% full width one column Footer Widget in Infinity Pro that looks and functions exactly like what you taught us to do for Altitude Pro (https://sridharkatakam.com/how-to-add-an-additional-footer-widget-area-in-altitude-pro/)?

I would like to be able to add a 100% full width one column Footer1 Widget in Infinity Pro.
I would also like to be able to add a 100% full width one column Footer2 Widget in Infinity Pro.
And, I would also like to be add a third 100% full width one column Footer3 Widget in infinity Pro.

I would also like the Footer Widgets to be able to be displayed on the homepage.

I would like the option to be able to set up a background image for a single footer widget with a dark overlay. So If you could demonstrate how to do this for Footer2 Widget, I would appreciate it.

For Footer1 widget I would like the background color to be set to #DE913B

For Footer3 widget I would like the background color to be set to #EEEEEE
